' HAY AND OTHER ELEVATORS.

SPECIFICATION forming part of Letters Patent No. 295,893, dated April 1, 1884.

Application filed December 20, 1883. (No model.)

To aZZ whom. it iii/my concern-,1

. Be it known that I, CHARLES S. AMERUSTER,

tial longitudinal vertical section of an elevator embodying my invention. Fig. 2 is a transverse vertical section in line mm, Fig. 1. Fig.

3 is a perspective view of a detached part. 15 Fig. 4 is a side elevation of a portion of Fig. l enlarged. Fig. 5 is avertical section in line 3 3/, Fig. 4. i Similar letters of reference'indicate corresponding parts in the several figures.

My invention consists of a traveler provided with means for rendering the same immovable during the elevation of the load and automatically releasing the traveler preparatory to moving it with the load to the required 2 5 cality.

\ ,It also consists of the construction of the hangers of the beam or track of the elevator, the support for the pulleys, and of said track, as will be hereinafter fully set forth.

Referring to the drawings, A represents a track or beam, which is suspended from the rafters or joists of a barn or other building or place, and on the same is supported the traveler B, the frame B whereof is provided with 3 5 pulleys O, which run on said track, and apulley, D, over which the elevating-rope E is passed, said rope also passing around a sheave, F, and is fastened to the frame B. The frame of the sheave F is provided with means for at- 4otaching it to a hay-fork or other device by i which a load may be taken. or grasped, the upper side of said frame having an eye, G, which is adapted to be engaged with the traveler, as will be hereinafter fully stated. To the frame B is pivoted a piece, H, the lower end whereof has a hook, H, said piece H being pivotally connected with a coupling or looking piece, J, which is also pivoted to the frame 13. The outer end of the coupling- 5 piece J has a head, a, which engageswith a notched piece or fork, K, the latter depending from and being secured to the track A, it being noticed that said fork K opens downward, and the coupling-piece J has vertical motions, and is adapted to enter andleave the fork K from below, thus connecting and disconnecting... the travelerwith and from said fork K. Projecting from the fork toward the traveler-is an arm, L, so disposed that when 1 the traveler approaches the fork said arm strikes a lug or projection, 12, on the upper part of the coupling-piece J, thus positively causing the latter to enter the fork and have its head engagetherewith. ,TheropeEalso passes around a pulley, M, secured to the track A at 6 5 a suitable distance fromthe fork K, and said pulley may be connected to the track or either side of the fork, so as to adapt the traveler to operate to the right or left, as desired, it being seen that the fork K and arm L are duplicated for said purpose.

The operation is as follows: When the parts are in their normal position, as in Fig. 1, and the hay-fork or other device is loaded, the rope E is drawn, thus raising the sheave and load, the traveler remaining locked in position. The

eye G enters an opening, d, in the bottom of A the frame B, and is thereby guided against the piece H, thusraising the same and cansing the coupling-piece J to lower and-clear itself of the fork K. The eye G, having moved along the hook H, past the end thereof, drops on the same, and as the rope E is continued to be drawn upon the traveler leaves its place, the strain on the rope preventing the load, or more 8 5 particularly the eyeG, from disengaging from the hook H. As soon as the traveler reaches the required locality,the hay-fork or other device is tripped or released and the load is discharged. The rope is let go and the traveler, o undertheaction of a counter-weight, N,which runs on a cord, P, suitably connected with the traveler and building, returns to its first position. As soon as the arm L strikes the lug or projection of the coupling-piece J, the latter is 5 raised and locked with the fork K; Simultaneously with this motion the hooked piece H is thrown down by the downward motion of the inner end of the coupling-piece J, and the hook H permits the eyeG to clearitself there- 10o the hooked piece H, I attach to the frame B a. spring. Q, so disposed that it bears at the back of said piece, at either the top or bottom thereof, according to the position of the piece, thus retaining said piece and preventing the same from rebounding when struck by the eye G, or premature movements during the subsequent manipulations of the elevator.

In order to attach the track or beam in position, I employ hangers R, which are flanged at bottom to take hold of the underside of the track, and have slots R at the top for the insertion of supporting-pins S with cross-barsor T-heads S, arrangedone above the other, and of width less than the length, so that when the pins are inserted in the slots R to the required extent and quarter-turned, the bars or heads engage with the walls of the sl ots, thus sustaining the hangers, the bars or heads admitting of the vertical adjustment of said hangers, and consequently of the track or beam. The upper ends of the hangers are recessed to receive the bars or heads S, whereby accidental disconnection of the pins and hangers is prevented, without, however, preventing such disconnection when required when the pins are properly manipulated. Thepins S are swiveled to eyes T, whereby they are permitted to be turned,

and said eyes have connected with them hooks V,which may be securely fastened to the rafters, joists, &c., of the building, it being noticed that the track or beam may be readily and conveniently hung in. position and taken down therefrom, as required. The track is formed of two lengths of rails, properly connected by blocks at intervals, forming a strong structure, and the traveler has two sets of rollers or pulleys, 0, running thereon, thus uniformly sustaining the traveler. The hangers R are passed through the space between the two rails, and the pulley D has its bolt passed through one of the blocks and sustained by means of a nut, which rests on a washer, IV, whose locality is on the top of the two rails, its contour being curved to conform to the head of the rails, whereby the washer is prevented from shifting.

The motions of the hooked piece H are limited by steps or lugs, suitably formed with or secured to said piece, and adapted to abut against the frame B when the piece is moved in either direction.

Having thus described my invention, wh atI claim as new, and desire to secure by Letters Patent, is-

1. A pivoted piece, H, provided with ahook, H, and attached to the carrier of an elevator for hay or other material, in combination with a pivoted coupling-piece, J, and an immovable vertically-slotted fork, K, said coupling-piece being adapted to engage with said piece H, and being locked by said fork for the purpose of holding the traveler stationary until the pieces H and J are thrown into proper position for disengagement by the contact of the eye G with the hook H, substantially as set forth.

2. The pivoted piece H, provided withhook H, in combination with devices for holdingand releasing the same, the eye G, which engages with said hook, and affords a means of suspension for a hay-fork or other device, and the spring Q, which bears at the back of piece H at either the top or bottom thereof, according to the position of the latter.

3. The fixed arm Land its roller, in combi nation with the pivoted and coupled pieces II and J, mounted in a traveler, and the fixed fork K, adapted to engage piece J and lock said traveler, said piece J being provided with a projection, 12, which is engaged by said arm or its roller,so as to force the said piece J into engagement with said fork.

4. In an elevator, a traveler having a pivoted hook and a pivoted coupling-piece, in combination with a spring adapted to hold the hook in raised and lowered positions, substan tially as and for the purpose set forth.

5. In an elevator, a hanger for the rail or beam of the traveler,formed with a slot,in com- V, combined and operating substantially as and for the purpose set forth.
